Specification of Letters Patent.

Iatented Oct. 20, 1908.

Application filed my 29,1908. Serial No. 435,641.

To all 'uiho'm 'it may concern:

Be it known that I, DANIEL J. MON'JAMBO, residing 1n Pentoga, 1n the county of Iron and State of Michigan, have invented new and useful Improvements in Brake-Wheels, of which the following is a description,-reference being had to the accompanying drawings, which are a part of this specification.

This invention has for its object to provide a brake wheel with convenient handles by which it may be turned instead of requiring a brakeman to grasp the rim, of the wheel as usual, such handles being pivotally mounted so as to be capable of swin ing beyond the rim of the wheel and provi ed with a guard to return them to their inward positions when the brake is released to prevent their injuring the brakeman. With the above and other objects in view the invention consists in. the brake wheel herein claimed, its

parts and combinations of parts and all equivalents.

Referring to the accompanying drawin s in which like characters of reference in icate the same parts in the several views; Figure 1 is an elevation of abrake wheel vconstructed in accordance with this invention mounted on the end of a box car; Fig. 2 is a plan view thereof; Fig. 3 is a central sectional view thereof; and, Fig. 4 is a detail view of the guard for returning the handles to their inward position.

Inthese drawin s 10 represents a brake shaft mounted on tile end of a box car 11 as usual with an ordinary ratchet 12 and its en aging dog 13 for locking it when it is ho ding the brakes. The brake wheel 14, which is mounted on the end of the shaft "in the ordinary manner, has each of its spokes 15, referably six in number, recessed or groove to form parallel flanges 16 between which. handle members 17 are pivoted so as to extend beyond the rim of the wheel or to lie within the housin therefor formed by the grooves in the w eel s okes. The longitudinalv grooves of the whee s okes are intercepted by transverse'g'rooves w ich permitthe operator to readily grasp the handles 17 when they are folded inwardly, so that they may be thrown to their outward position where the are supported'against moving downwardly by engaging the rim of the 7 wheel, as clearly shown in Fig. 3; Bymeansof these pivoted handles 17 the brakeman may secure a reater leverage in applying the brakes as t 'ey extend beyond the rim of provided which is supported alongside of the brake wheel and is of an arc shape, both vertically and horizontally, with its ends beginning below the level of the extended handles and its middle portion extending considerably higher, so'that the quick movement of the brake wheel, as when the brake is released, will cause the handles to ride up the inclined surface of the guard 1.8 wit such force that they will be thrown over their pivotal connections to fall inwardly and thus be revented fromstriking the brakeman. T e effect of the guard 18 is to throw the handles 17 inwardly only when the are moving rapidly, permitting them to ri' e up and down over it without falling inwardl during the slower motion ofthe brake whee as when the brakes are being applied. Any suitable support may be given to the guard 18, as shown there being a bent metalrod 19 with cross arms 20 at its lower end secured to the car body and a clip 21 at its u per part surroundingthe brake shaft 10. bviously the rod 19, instead of having its crossed arms 20 secured to the end of the car body, may be bent so that said rod rests upon the roof of the car so as to be secured thereto. i

From the foregoing it will be seen that by the present invention the brakeman is a forded a better hand-hold on the brake wheel with the advanta e of a eater leverage for applying the bra es an the automatic-retrieving means for the pivoted handles serve to withdraw 1 them from the position where they might strike him and cause injury during the rapid rotation of the brake wheel when the brakes are released.

What I claim as m invention is;

1. A brake wheel aving gi'ooved spokes and a rim, and handlespivota (y mountedin' the grooves of the .spokes an adapted to swing to a position where they extend beyond the rim to afford a convenient handhold .and 'to swing to an inward position within the grooves.

2. A brake wheel having grooved spokes and a rim, and handles pivotally mounted in the grooves and adapted to swing to a position wherethey extend beyond the rim to afford a convenient hand-hold with their sides confined within the grooves and supported 7 by bearing onthe bottom of the grooves and 0 adapted to be swung inwardly within the ooves, there being transverse openings in t e spokes to permit of access to-the handles when swun inwardly. 4

- 3. A brake whee, comprising a wheel member, pivoted handles mounted thereon adapted to swin outwardly beyond the rim of the wheel, an a guard located in the path wheel moves quickly as on the release of the brakes, but permitting them to move thereon without being thrown inwardly when the brake wheel moves slowly as during the application of the brakes. I

5. A brake wheel, comprising a brake. shaft, a wheel member mounted thereon,

handles pivotally mounted on the wheel member and lprojecting beyond the rim thereof, a rod avlng cross arms adapted to be secured to the car body, a clip on the rod engaging a brake shaft, and a curved are shaped guard mounted on the rod inlthe path of the handles adapted to. cause them to swing to their inward position when they. are moved past it on releasin the brake.

In testimony whereof, aflix my signature,

in presence of two witnesses. v
